Any compound (not being Bupropion, Cathinone, Diethylpropion, Pyrovalerone or a compound for the time being specified in sub-paragraph (a) above) structurally derived from 2-Amino-1-phenyl-1-propanone by modification in any of the following ways, that is to say,

by substitution in the phenyl ring to any extent with alkyl, alkoxy, alkylenedioxy, haloalkyl or halide substituents, whether or not further substituted in the phenyl ring by one or more other univalent substituents;

by substitution at the 3-position with an alkyl substituent;

by substitution at the nitrogen atom with alkyl or dialkyl groups, or by inclusion of the nitrogen atom in a cyclic structure.

Only a handful of the Cathinone analogues captured by this amendment are shown below. For a more comprehensive enumeration, I highly recommend Synchronium’s elegant depiction, an inspiring model of information design.
